ABSTRACT
Even today many microcontroller making interfacing with the seven segment and Lcd display which is appliance in several electronics devices.
Through the microcontrollers serves the many information like decorating product, saffosticatedcampus,games zones etc.
The project is attemted to developed a totally electronically based system, which provide a better communication between the unknown sarvent and condition which is applied on that atmosphere. The present project only helps to indicating the result that’s provided by microcontroller counting.
INTRODUCATION
This project is basedon the concept is that interfacing microcontroller with the seven segment display. In this project we made two circuit first one is based on our main concept to seven segment interfacing the circuit, and second one circuit is for turning on/off the display by switch appliance or activate this circuit means it is a reset circuit. We can activate this circuit from the power supply of 12 volt bettarycircuit from a ic7805 to 5 voltsupply. The 5 volt supply interfaced between the microcontroller and seven segment generated by connection of port 2 pin which is connected by serially the reset swicth which placed on the main circuit and activate the circuit when we push the switch circuit button.
COMPONENT
• Microcontroller (AT89C51)
• Seven segment
• Ic 7805
• Switchs
Microcontroller(AT89C51):-
pin AT89C51, there are four port designated as p1, p2, p3, p0. All these ports are 8-bit bidirectional port, i.e., they can used as both input and output ports. Except p0 which needs external pull-ups, rest of the ports have internal pull-ups.when 1s are written to these port pins, they are pulled high by the internal pull-ups and can be used as input. These ports are also bit addressable and so their bit can also be accessed individually.
Flash AT89C51 is an 8-bit microcontroller and belong to atmel’s 8051 family. ATEL 89C51 has 4KB programmable and erasable read only memory (PEROM) and 128 bytes of RAM. It can be erased and program to a maximum of 1000 times.
Seven segment display:-
A seven segment display is most basic electronics display digit from 0-9. They find wide application in devices that display numeric information like digital clocks, radio, microwave ovens, electronic meter etc. the most common configuration has an array of eight led arranged in a special pattern to display these digit. They are laid out as a squared-off figure ‘8’. Every led is assigned name from ‘a’ to ‘h’and is identified by its name.seven led ‘a’ to ‘g’ are used to display the numerals while eighth led ‘h’ is used to display the dot/decimal.
POWER SUPPLY:-
9V-12V power supply is given to the IC 7805, which convert it into 5Vdc. The power supplies to the entire blocks are different as –
